本发明实施例涉及音频处理技术领域，尤其涉及一种歌曲音频处理的方法及装置。The embodiments of the present invention relate to the technical field of audio processing, in particular to a method and device for audio processing of songs.
背景技术Background technique
随着移动互联网技术的快速发展，装置(如手机、平板电脑、touch)及专用播放机等对音乐的追求也越来越来。目前来看，现有技术中对音乐的功能播放仅限于提高自身的音质处理，如通过装置或者专用播放机中自带的处理软件对劣质音频文件进行适当处理，以提高播放质量；或者，对音频文件本身的质量要求较高，往往正版音频文件能播出较好的效果，而对音频文件的局部处理，如切割技术、提取技术研究较少。With the rapid development of mobile Internet technology, devices (such as mobile phones, tablet computers, touches) and dedicated players are increasingly pursuing music. At present, the functional playback of music in the prior art is limited to improving its own sound quality processing, such as properly processing low-quality audio files through the processing software that comes with the device or a dedicated player to improve the playback quality; The quality requirements of the audio file itself are relatively high, and often genuine audio files can play better results, but there is little research on the partial processing of audio files, such as cutting technology and extraction technology.
现有技术中，对歌曲的剪切主要依赖于网络软件，而这些软件往往需要人工手工操作，不能精确定位每一句歌词的确切位置。In the prior art, the cutting of songs mainly depends on network software, and these software often require manual operation, and cannot accurately locate the exact position of each lyric.

请参阅图1，图1是本发明实施例提供的一种歌曲音频处理的方法的第一实施例流程示意图。本实施例中所描述的歌曲音频处理的方法，包括步骤：Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a first embodiment of a method for processing song audio provided by an embodiment of the present invention. The method for song audio processing described in the present embodiment, comprises steps:
S101、获取N个歌曲音频文件。S101. Acquire N song audio files.
具体的，获取N个歌曲音频文件，可从歌曲音频处理装置中获取；也可以从另一装置中获取；例如蓝光播放机挂载的存储设备或移动终端，所述移动终端例如可以是手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(MID，mobile internet device)、可穿戴设备(例如智能手表(如iwatch等)、智能手环、计步器等)或其他可安装部署即时通讯应用客户端的终端设备，或是从云端中获取、或从网络中获取等等。其中，N为大于或等于1的整数。Specifically, the acquisition of N song audio files can be obtained from the song audio processing device; it can also be obtained from another device; for example, a storage device mounted on a Blu-ray player or a mobile terminal, and the mobile terminal can be, for example, a mobile phone, Tablet computer, laptop computer, handheld computer, mobile Internet device (MID, mobile internet device), wearable device (such as smart watch (such as iwatch, etc.), smart bracelet, pedometer, etc.) or other instant messaging applications that can be installed and deployed The terminal device of the client is either obtained from the cloud, or obtained from the network, and so on. Wherein, N is an integer greater than or equal to 1.
S102、分析所述N个歌曲音频文件，以确定所述N个歌曲音频文件中的M个语句片段。S102. Analyze the N song audio files to determine M sentence segments in the N song audio files.
具体的，分析所述N个歌曲音频文件，以确定所述N个歌曲音频文件中的M个语句片段，可以是分析所述N个歌曲音频文件携带的歌词信息，以确定所述N个歌曲音频文件中的M个语句片段，也可以是通过接收所述N个歌曲音频文件的音频内容，通过音频内容歌词空挡位置，确定所述N个歌曲音频文件中M个语句片段，或是其他方式分析所述N个歌曲音频文件，以确定所述N个歌曲音频文件中的M个语句片段。Specifically, analyzing the N song audio files to determine the M sentence segments in the N song audio files may be analyzing the lyrics information carried by the N song audio files to determine the N song audio files The M sentence fragments in the audio file can also be determined by receiving the audio content of the N song audio files, and determining the M sentence fragments in the N song audio files through the blank position of the audio content lyrics, or in other ways Analyzing the N song audio files to determine M sentence segments in the N song audio files.
S103、从所述N个歌曲音频文件中提取所述M个语句片段。S103. Extract the M sentence segments from the N song audio files.
具体的，根据确定得到的所述N个歌曲音频文件中的M个语句片段，提取所述M个语句片段，其中，所述M为大于1的整数，每个语句片段为为每个独立的语句。Specifically, extract the M sentence fragments according to the determined M sentence fragments in the N song audio files, wherein, the M is an integer greater than 1, and each sentence fragment is for each independent statement.
S104、按照预设顺序将所述M个语句片段进行拼接，以得到拼接歌曲音频文件。S104. Splice the M sentence segments according to a preset sequence to obtain a spliced song audio file.
具体的，将提取到的所述M个语句片段按照预设顺序进行拼接，以获取拼接歌曲。其中，所述预设顺序可包括但不仅限于：时间先后顺序、随机顺序、用户自己预先设置的顺序等等。Specifically, the extracted M sentence segments are spliced according to a preset order to obtain spliced songs. Wherein, the preset order may include but not limited to: chronological order, random order, order preset by the user, and the like.
作为一种可能的实施方式，在多首歌曲的拼接中，根据所述变化规律将所述预设构成部分中重复度相同的且连续的语句合成段落，其中，语句为每首歌中独立的句子，进一步地，歌曲中语句的重复度计算方式可是统计一首歌中语句的总数，分别计算每个语句的概率，将相同语句的语句的概率进行相加，将相同语句的每个语句的概率定义为相加后的概率。判断预设构成部分中是否包含重复度超过预设阈值的段落，其中，预设阈值的定义方式可为：计算每个语句的概率，而预设阈值大于每个语句的概率。若预设构成部分中包含重复度超过预设阈值的段落，获取预设构成部分中超过所述预设阈值的段落对应的起始时间和结束时间。此种方式，根据起始时间和结束时间对所述歌曲音频文件进行切割操作，以得到歌曲音频文件中起始时间结束时间对应的切割段落，即高潮部分。As a possible implementation, in the splicing of multiple songs, according to the change rule, the repeated and continuous sentences in the preset components are synthesized into paragraphs, wherein the sentences are independent in each song. Sentences, further, the way to calculate the repetition degree of sentences in a song can be to count the total number of sentences in a song, calculate the probability of each sentence separately, add the probabilities of the sentences of the same sentence, and calculate the probability of each sentence of the same sentence Probability is defined as the summed probability. It is judged whether the preset constituent part contains paragraphs whose repetition degree exceeds a preset threshold, wherein the preset threshold is defined by: calculating the probability of each sentence, and the preset threshold is greater than the probability of each sentence. If the preset constituent part contains a paragraph whose repetition degree exceeds the preset threshold, the start time and end time corresponding to the paragraph exceeding the preset threshold in the preset constituent part are acquired. In this way, the song audio file is cut according to the start time and end time, so as to obtain the cut paragraph corresponding to the start time and end time in the song audio file, that is, the climax part.
可选的，在获取N个歌曲音频文件之前，将所述N个歌曲音频文件转换为预设格式的音频文件，通常情况下，不同格式的歌曲音频文件采用的编码方式不一样，因而会出现不同的格式类型。如何快速实现歌曲拼接，可在获取N个歌曲音频文件之前，对将所述N个歌曲音频文件转换为预设格式的音频文件。如将所有的歌曲音频文件转化为MP3格式或者WAV格式。Optionally, before obtaining the N song audio files, the N song audio files are converted into audio files of a preset format. Usually, song audio files of different formats use different encoding methods, so there will be Different format types. How to quickly implement song splicing, before acquiring the N song audio files, convert the N song audio files into audio files in a preset format. Such as converting all song audio files into MP3 format or WAV format.
作为一种可能的实施方式，可将，在获取N个歌曲音频文件之后，将所述N个歌曲音频文件转换为预设格式的音频文件。As a possible implementation manner, after acquiring the N song audio files, the N song audio files may be converted into audio files of a preset format.
可选的，在按照预设顺序将所述M个语句片段进行拼接，以得到拼接歌曲音频文件之后，为了实现拼接歌曲的无缝拼接效果，因此需要锁定所述拼接歌曲音频文件的拼接位置；将所述拼接歌曲音频文件的拼接位置进行处理，以获取无缝拼接歌曲音频文件。Optionally, after splicing the M sentence segments according to a preset order to obtain the spliced song audio file, in order to realize the seamless splicing effect of the spliced song, it is necessary to lock the spliced position of the spliced song audio file; The splicing position of the spliced song audio file is processed to obtain the seamlessly spliced song audio file.
具体的，将拼接歌曲音频文件的拼接位置进行处理，以获取无缝拼接歌曲音频文件。其中，处理可包括但不仅限于：对拼接歌曲音频文件的拼接位置进行曲调调整、插入变化程度相似的曲调、对变化幅度的拼接位置进行平滑处理。Specifically, the splicing positions of the spliced song audio files are processed to obtain seamlessly spliced song audio files. Wherein, the processing may include but not limited to: adjusting the tune of the splicing positions of the spliced song audio files, inserting tunes with similar variation degrees, and smoothing the splicing positions of the varying ranges.
